FIELD OF THE INVENTION

[0002] This invention relates to pyrazole derived compounds useful for treating p38 kinase-associated conditions. The invention further pertains to pharmaceutical compositions containing at least one compound according to the invention useful for treating p38 kinase-associated conditions, and methods of inhibiting the activity of p38 kinase in a mammal.

BACKGROUND OF THE INVENTION

[0003] A large number of cytokines participate in the inflammatory response, including IL-1, IL-6, IL-8 and TNF-α. Overproduction of cytokines such as IL-1 and TNF-α are implicated in a wide variety of diseases, including inflammatory bowel disease, rheumatoid arthritis, psoriasis, multiple sclerosis, endotoxin shock, osteoporosis, Alzheimer's disease, and congestive heart failure, among others [Henry et al., Drugs Fut., Vol. 24 (1999), at pp. 1345-54; Salituro et al., Curr. Med. Chem., Vol. 6 (1999), at pp. 807-823]. Evidence in human patients indicates that protein antagonists of cytokines are effective in treating chronic inflammatory diseases, such as, for example, monoclonal antibody to TNF-α (Enbrel) [Rankin et al., Br. J. Rheumatol., Vol. 34 (1995), at pp. 334-42], and soluble TNF-α receptor-Fc fusion protein (Etanercept) [Moreland et al., Ann. Intern. Med., Vol. 130 (1999), at pp. 478-86].

[0004] The biosynthesis of TNF-α occurs in many cell types in response to an external stimulus, such as, for example, a mitogen, an infectious organism, or trauma. Important mediators of TNF-α production include the mitogen-activated protein (MAP) kinases, a family of Ser/Thr protein kinases that activate their substrates by phosphorylation. The MAP kinases are activated in response to various stress stimuli, including but not limited to proinflammatory cytokines, endotoxin, ultraviolet light, and osmotic shock.

[0005] One important MAP kinase is p38 kinase, also known as cytokine suppressive anti-inflammatory drug binding protein (CSBP) or IK. Activation of p38 requires dual phosphorylation by upstream MAP kinase kinases (MKK3 and MKK6) on threonine and tyrosine within a Thr-Gly-Tyr motif characteristic of p38 isozymes. There are four known isoforms of p38, i.e., p38-α, p38β, p38γ, and p38δ. The α and β isoforms are expressed in inflammatory cells and are key mediators of TNF-α production. Inhibiting the p38α and β enzymes in cells results in reduced levels of TNF-α expression. Also, administering p38α and β inhibitors in animal models of inflammatory disease has established the effectiveness of p38 inhibitors in treating those diseases. The present invention provides pyrazole derived compounds, useful as kinase inhibitors, in particular, as inhibitors of p38 kinase.

Suitable protecting groups for the methods and compounds described herein include, without limitation, those described in standard textbooks, such as Greene, T. W. et al., Protective Groups in Organic Synthesis, Wiley, N.Y. (1999).

[0056] The term “selective” as used herein with reference to the capability of the claimed compounds to inhibit p38 activity means that the compound in question has a level of activity as measured in enzyme assays for inhibiting the p38 α/β kinase that is significantly greater than the activity of the compound in inhibiting a plurality of other kinases falling within families throughout the human kinome. The term “significantly greater activity” includes the activity of at least one compound having about 500-fold or more greater activity for inhibiting p38α/β enzyme as compared with the activity of the compound in inhibiting other kinases, for example, as compared with the activity of the compound in inhibiting about twenty-five or more other kinases, in another example, as compared with about fifty or more other kinases, and in yet another example, as compared with about 110 or more other kinases. Thus, a selective p38 inhibitor as defined herein according to one embodiment will inhibit the α-isoform of the p38 kinase, the β-isoform of the p38 kinase, and/or both the α and β forms of the p38 kinase, at least 500 times greater than it will inhibit any one of a plurality of other kinases. Thus, for example, considering an embodiment involving comparison with a sample of twenty-five other kinases, p38 selective compounds will have 500 times greater activity in inhibiting p38α/β kinase as compared with any one of each of the twenty-five other kinases considered individually (e.g., in a one-on-one comparison). In another embodiment of the invention, compounds are provided having at least about 1,000-fold greater activity for inhibiting p38 α/β kinase as compared with other kinases, for example, as compared with about twenty-five or more, about fifty or more, and in yet another example, as compared with about 100 or more other kinases. In yet another embodiment of the invention, compounds are provided having at least about 5,000-fold greater activity for inhibiting p38 α/β kinase as compared with other kinases, for example, as compared with about twenty-five or more other kinases, as compared with about fifty or more other kinases, and in yet another example, as compared with about 100 or more other kinases. The term “highly selective” as used herein means the compound in question has at least about 10,000 fold greater activity for inhibiting the p38 α/β kinase enzyme as compared with at least thirty other kinases, more preferably, as compared with at least about fifty or more other kinases. When reference is made herein to “other kinases”, applicant intends to refer to kinases known in the field other than the p38 α/β kinases. For example, various known kinases and kinase families other than the 38 α/β kinase are identified in WO 02/062804, and in Manning, G.et al., The Protein Kinase Complement of the Human Genome, Science (Washington, D.C., United States) (2002), 298(5600), at pp. 1912-1916, 1933-1934, which is incorporated herein by reference. “Other kinases” as identified therein thus may include, without limitation, one or more kinases chosen from the following kinases and/or kinase families: CaMK1, CaMK2, CDK, DAPK, EMT, FGF, FMS, GSK3, LCK, PDGF-R, PKA, PCK, RAF, RIPK, LIMK-1, SYK, Met, PAK-4, PAK-5, ZC-1, STLK-2, DDR-2, Aurora 1, Aurora 2, Bub-1, PLK, Chk1, Chk2, HER2, JAK, raf1, MEK1, EGF-R, RSK/RSK, IGF-R, IRAK, VEGF-R, P13K, PDK, HIPK, STKR, BRD, Wnk, NKF3, NKF4, NMKF5, weel kinase, Src, Ab1, ILK, MK-2, IKK-2, RIPK, Cdc7, Ste11, Ste20, Ste7, Tec, Trk, and/or Nek, and so forth. The above is an exemplary, non-limiting list of other kinases. Manning identified 518 protein kinases, and applicant intends to incorporate each one of these 518 protein kinases other than the p38 kinase in the definition of the term “other kinases” as used herein.

Accordingly, compounds of formula (I) have utility in treating conditions associated with p38 kinase activity. Such conditions include diseases or disorders in which cytokine levels are modulated as a consequence of intracellular signaling via p38, and in particular, diseases that are associated with an overproduction of cytokines IL-1, IL-4, IL-8, and TNF-α. As used herein, the terms “treating” or “treatment” encompass responsive and/or prophylaxis measures addressed to the disease state and/or its sypmtoms, e.g., measures designed to inhibit or delay the onset of the disease or disorder, achieve a full or partial reduction of the symptoms or disease state, and/or alleviate, lessen, or cure the disease and/or its symptoms. When reference is made herein to inhibition of “p-38α/β kinase,” this means that either or both p38α and p38β kinase are inhibited.

[0126] In view of their activity as inhibitors of p-38α/β kinase, compounds of Formula (I) are useful in treating inflammatory diseases, autoimmune diseases, destructive bone disorders, proliferative disorders, angiogenic disorders, infectious diseases, neurodegenerative diseases, viral diseases, and ischemia reperfusion conditions.

Biological Assays

[0163] Generation of p38 Kinases

[0164] cDNAs of human p38α, β and γ isozymes are cloned by PCR. These cDNAs can be subcloned in the pGEX expression vector (Pharmacia). GST-p38 fusion protein is expressed in E. Coli and purified from bacterial pellets by affinity chromatography using glutathione agarose. p38 fusion protein is activated by incubating with constitutively active MKK6. Active p38 is separated from MKK6 by affinity chromatography. Constitutively active MKK6 is generated according to Raingeaud et al. [Mol. Cell. Biol., 1247-1255 (1996)].

[0165] TNF-α Production by LPS-Stimulated PBMCs

[0166] Heparinized human whole blood is obtained from healthy volunteers. Peripheral blood mononuclear cells (PBMCs) are purified from human whole blood by Ficoll-Hypaque density gradient centrifuguation and resuspended at a concentration of 5×10⁶/ml in assay medium (RPMI medium containing 10% fetal bovine serum). 50 ul of cell suspension is incubated with 50 ul of test compound (4× concentration in assay medium containing 0.2% DMSO) in 96-well tissue culture plates for 5 minutes at RT. 100 ul of LPS(200 ng/ml stock) is then added to the cell suspension and the plate is incubated for 6 hours at 37° C. Following incubation, the culture medium is collected and stored at −20° C. TNF-α concentration in the medium is quantified using a standard ELISA kit (Pharmingen-San Diego, Calif.). Concentrations of TNF-α and IC₅₀ values for test compounds (concentration of compound that inhibited LPS-stimulated TNF-α production by 50%) are calculated by linear regression analysis.

[0167] p38 Assay

[0168] The assays are performed in V-bottomed 96-well plates. The final assay volume is 60 μl prepared from three 20 μl additions of enzyme, substrates (MBP and ATP) and test compounds in assay buffer (50 mM Tris pH 7.5, 10 mM MgCl₂, 50 mM NaCl and 1 mM DTT). Bacterially expressed, activated p38 is pre-incubated with test compounds for 10 min. prior to initiation of reaction with substrates. The reaction is incubated at 25° C for 45 min. and terminated by adding 5 μl of 0.5 M EDTA to each sample. The reaction mixture is aspirated onto a pre-wet filtermat using a Skatron Micro96 Cell Harvester (Skatron, Inc.), then washed with PBS. The filtermat is then dried in a microwave oven for 1 min., treated with MeltilLex A scintillation wax (Wallac), and counted on a Microbeta scintillation counter Model 1450 (Wallac). Inhibition data are analyzed by nonlinear least-squares regression using Prizm (GraphPadSoftware). The final concentration of reagents in the assays are ATP, 1 μM; [γ-³³P]ATP, 3 nM,; MBP (Sigma, #M1891), 2,μg/well; p38, 10 nM; and DMSO, 0.3%.

[0169] TNF-α Production by LPS-Stimulated Mice

[0170] Mice (Balb/c female, 6-8 weeks of age, Harlan Labs; n═8/treatment group) are injected intraperitoneally with 50 ug/kg lipopolysaccharide (LPS; E coli strain 0111 :B4, Sigma) suspended in sterile saline. Ninety minutes later, mice are sedated by CO₂:O₂ inhalation and a blood sample was obtained. Serum is separated and analyzed for TNF-alpha concentrations by commercial ELISA assay per the manufacturer's instructions (R&D Systems, Minneapolis, Minn.).

[0171] Test compounds are administered orally at various times before LPS injection. The compounds are dosed either as suspensions or as solutions in various vehicles or solubilizing agents.
